Hi, I just want to share my experience as it might be useful for others.
I have a small Yamaha receiver HTR-5230 with very cheap speakers (centrios). I love to listen to music. I bought the Klipsch F2 speakers (350$ for a pair) thinking that I would feel a difference. It was not the case! I found F2: too bright, lack of mid, harsh, a lot of distortion and... painful! I brought back these F2 speakers to the store and bought Polk Rti10 (580$ for a pair!). I love these speakers! With my Polk 10" Subwoofer, I think I found the perfect match!
